What is alsways helping me was apt-get --purge remove `nvidia-*` or alternatively aptitude purge ~nnvidia-* (not a typo, it is ~nnvidia-*) Hope this helps. Good luck!

Instaled nvidia from an alternate source an ran into problems because not packaged for Debian. Probem is I cannot uninstall old version because dpkg halts: Welcome to the NVIDIA Software Installer for Unix/Linux Detected 8 CPUs online; setting concurrency level to 8. If you plan to no longer use the NVIDIA driver, you should make sure that no X screens are configured to use the NVIDIA X driver in your X configuration file. If you used nvidia-xconfig to configure X, it may have created a backup of your original configuration. Would you like to run `nvidia-xconfig --restore-original-backup` to attempt restoration of the original X configuration file? [default: (N)o]: N Progress: [ 0%] [..................................................................] this does not even return the prompt. After this I can no longer update system apt refuses to run dist-upgrade. SO, how can I uninstall old version of nvidia?
